September 30, 2018 A few weeks ago I published the first version of the systems library for modeling systems dynamics. Today I cut a second version with improved support for itereating on models in Jupyter notebooks.

September 26, 2018 A peculiar challenge of management is trying to invest in someone's career development when they themselves are uncertain about their goals. As a manager, you may have more experience and more access to opportunities within the company, but that represents a small slice of their career possibilities.

September 23, 2018 Some years back, I was sitting in a room with my manager, our CTO and a crisis. An engineer on my team had mishandled two alerts, which had cascaded into plausibly the worst production incident the company had experienced to date. There were three root causes: alert fatigue, a lack of velocity context for out-of-diskspace alerts, and relying on a centralized database with little support for vertical scaling. At that moment, though, we were no longer talking about root causes. We were discussing whether to fire the oncall engineer, and I was saying no.
